This guy is an absolute genius. At 5:23 he changes key very swiftly and plays with this key until 5:53 where he goes back to original key. The way he does it is so amazing you could tell by the back up singer's reactions
starting at 5:04 his chord progressions made me feel like the left side of my face was in a Blackhole and the right side of my face was in a fiery furnace.
